TELEPHONE-MOUTHPIEC GUARD.

Specification of Letters Patent. Patollted SQPT. 28, 1909.

Y Application filed April 3, 1909. Serial No. 487,633:

To all who/m it may concern:

Be it known that I, LiNnnN H. lVnsTEn, a c'tizen of the United Statesresiding at li yiidere, in the county of Allegany and et New 7ork, have'invented new and useia improvements in Teleplione-B'Ioutlr piece Guards, of' which the-following is a specification` The invention relates to an improvement in guards for the mouthpiece of a telephone transmitter, and is particularly directed to a structure designed for removable cGp/eration with the mouthpiece and serving in use to prevent contact between the lips of the user and the mouthpiece and to also position the mouth of the user a proper distance from the mouthpiece of the instrument for the most effective use.

The main object of the present invention is the provision of a guard constructed in skeleton form and embodying a mouth ring and a clamping ring with means for secur ing the latter about the mouthpiece of the instrument, the clamping ring andmouthpiece being connected so as to space the former the proper distance from the free edge of the mouthpiece. I

The invent-ion will be described in the following specification, reference being had particularly to the accompanying drawings, in which Figure l is a View in elevation, illustrating the application of the improved guard.

Fig. 2 is a perspectiveview of the guard.

Fig. 3 isa bottom plan view of the saine.

{eferring particularly to the accompanying drawings, the improved guard in its preferable form'is constructed of lengths of wire, one of which is bent adjacent one end to form a mouthpiece l of an appropriate diameter, the terminals of the Wire length being intertwisted at 2 to maintain the ring formation, one of said terminals being projected beyond the intertwisted.portion and at rightangles to the plane of the ring to provide a supporting arm 3. The other wire section is bent about centrally of its length to provide what is termed a clamping ring 4, said material at an appropriate pointA ,in the ring surface being bent to provide spaced eyes 5, which are arranged in horizontal alinement tangentially of the clamping ring. From the c ves the materia-l is projef-led to provide divergent supporting arms The supporting arms 3 and 5 are of approximately the same length and the free terminal of the former is designed to be coiled about .or otherwise engaged with the -clamping ring 4 at a point diamet-rically opposite the eyes 5, while the latter at their free ends are coiled or otherwise connected at spaced pointsto themouth ring l. By this construction the mouth ring and clamping ring are maintained in spaced parallel relation, connected at their relatively upper portions by a supportingfarm and at their lower portions by a pair of non-parallel supporting arms. A headed bolt 7 is designed to engage the alined eyes 5 and the clamping ring, said bolt being threaded for the reception of a nut 8, whereby the eyes 5 may be adjusted with relation to each other to practically'increase or decrease the diameter of the clamping ring.

' By preference the material forming the clamping ring 4 is of sinuous outline in order to permit the cooperation of thel ri-ng with mouthpieces of different sizes, it being obvious that by virtue of such formation the clamping action of the nut will in the event piece of unusual size permit the material t'orming said ring to straighten to a greater or less degree to accommodate such mouthpiece.

the niitter, being arrangedv adjacent the connection of said mouthpiece with the instrument. The arms 3 and 6 are of such length to space the mouth ring l in advance of the forward edge of the mouthpiece 10, the disthe user will be so spaced from the mouthpiece of the instrument as to insure a proper talking eiiect without the usual jarring and harshness incident to a close application of the mouth of the user tol the mouthpiece of the instrument.

It is obvious that the mouth ring will prevent contact of the lips ot the user with the mouthpiece of the instrument, andv thereby avoid transmission. ot disease or the like possibly incident to such contact` 1V bile preferring that the guard be constructed of wire as described, it is-obvious that it would be equally eliective when constructed of any well known material.
